Hello,
today one of our system got a kernel bug message. It kept on running
but more and more process begin to be stuck in D state (eg. a simple w
command would never return) and I eventually had to reboot. Here the
full message:

Kernel is a plain kernel.org kernel 3.12.9 and it uses drbd to replicate
data to another host. Any idea what the cause of this bug is? Could it be
hardware? The system has been running now for five years without any problems.
Please CC me since I am not on the list.
Many thanks in advance.
Regards,
Holger

Please, tell me if you do not get the attachment. I hoped it would help me to get a closer compiled code to yours but I am probably using too different gcc. Anyway I've tried to check whether I can hook on something and it seems that this is a race with thp merge/split or something like that.

Holger, this looks like a race condition when allocating a compound page, did you only see it once or is it actually reproducible? I think this happens when a new compound page is allocated and PageBuddy is cleared before prep_compound_page() and then we see PageTail(p) set but p->first_page is not yet initialized. Is there any way to avoid memory barriers in compound_page()? ^ permalink raw reply [flat|nested] 14+ messages in thread

* [patch -mm] mm: close PageTail race 2014-02-05 8:42 ` Michal Hocko @ 2014-02-12 9:00 ` David Rientjes 0 siblings, 0 replies; 14+ messages in thread From: David Rientjes @ 2014-02-12 9:00 UTC (permalink / raw) To: Andrew Morton Cc: Andrea Arcangeli, Mel Gorman, Rik van Riel, Kirill A. Shutemov, linux-kernel, linux-mm Since "mm, compaction: avoid isolating pinned pages", it has been possible for page_count(page) to race with prep_compound_page() by finding PageTail(page) set with a NULL or dangling page->first_page. "mm, page_alloc: make first_page visible before PageTail" adds a store memory barrier to prep_compound_page() to ensure page->first_page is set, but nothing is preventing compound_head() from seeing a dangling head page. This patch uses Andrea's implementation of compound_trans_head() that deals with such a race and makes it the default compound_head() implementation. This includes a read memory barrier that ensures that if PageTail(head) is true that we return a head page that is neither NULL nor dangling. This is the safest way to ensure we see the head page that we are expecting, PageTail(page) is already in the unlikely() path and the memory barriers are unfortunately required. Hugetlbfs is the exception, we don't enforce a store memory barrier during init since no race is possible.
